Went to a Rolling Road Day at Alan Jefferys, with a local car club called Tuning House. I couldn't resist the chance to see how the Sierra would fair. The result............  ............A result I am proud of ;D Bearing in mind that the 2.0 EFi Pinto has done 116,000 miles in the last 19 years it made very close to the 115 bhp that Ford quoted out of the factory. The 4-2-1 manifold and ashley exhuast probably helped to make that figure. But either way I am happy with it and it give a great bench mark before the turbo gets fitted! Really need to get on with it! |

pinto-turbo-nom-nom-nom. What does it take, a CR lowering plate/piston change?? intercooler and associated gubbins and an uprated oil pump?? Still gonna be rocking EFi? Stick some skinny tyres or ditchfinders on the back and you wont have to worry about breaking stuff either  D |

Standard CR. and interals will support up to 10-12 psi with enough ignition retard. I want to run 6 psi although I am sure that I push it up as far as my balls allow The standard injectors will flow enough for 150 bhp providing that I can adjust the fuel pressure correctly (so the EFi is staying) Already got a suitable intercooler, i/c pipes and lots of other bit and pieces (check my build thread, link in my sig) |

Take AJs rollers with a pinch of salt I was on the understanding that AP motors RR was a lot more optimistic. My mates 318is made 141 bhp on AJ RR, on Fritz Bitz RR it make 150+ bhp a few weeks previous. I am fairly confident that AJ is probably the most acurate locally. Flywheel, forgot to ask what the reading was at the wheels! I guess it's quite a loss though ;D |

you cannot measure BHP at the flywheel on a rolling road. You can only estimate it. It is also pointless comparing a rolling road estimate of flywheel power to the manufacturers stated power output as the correction factors used for air pressure, temperature, etc. used by rolling roads are different to those used by the manufactorers crank dyno cell. Even the standard factor used by aftermarket crank dyno cell will not be the same as the OE one.
Rolling roads should be used as a baseline for tuning. So you show 111 BHP now, after your mods you go, you tune on the road and the rollers and then see what the difference to the curve is and what the new headline figure is.
I'd be more interested to see what the RWHP figure was before they "estimated it to crank". Had some guy on another forum with a 100 BHP Mini. Had a rolling road printout to prove it. But the measured at the wheels figure was 30 BHP! I don't believe like 225% transmission losses, even in a Mini.
Rolling road shootouts are allways good fun for braggin' rights though.
